MEDICAL DEVICE INCLUDING CORRUGATED BRAID AND ASSOCIATED METHOD
First Claim
1. A medical device for treating a target site within the body, the medical device comprising:
- a tubular structure having proximal and distal ends and a side wall extending therebetween, at least a portion of the side wall having a corrugated surface, the tubular side wall comprising at least one layer of a metallic fabric configured to be compressed and heat set to define the corrugated surface.

Abstract
Embodiments of the present invention provide medical devices for treating a target site within the body and associated methods for fabricating and delivering medical devices. According to one embodiment, a medical device includes a tubular structure having proximal and distal ends and a side wall extending therebetween. At least a portion of the side wall can have a corrugated surface. The side wall further includes at least one layer of a metallic fabric configured to be compressed and heat set to define the corrugated surface. The tubular structure may comprise an expanded shape, and may be configured to be constrained to a smaller diameter than the expanded shape for delivery within a catheter to a target site and to assume the expanded shape upon release from the catheter.

12. A method for increasing the radial strength of a medical device comprising:
-
providing a tubular structure comprised of at least one layer of metallic material and having proximal and distal ends and a side wall extending therebetween; compressing the tubular structure such that the side wall defines at least one corrugated surface extending at least partially between the proximal and distal ends; and heat setting the compressed tubular structure. - View Dependent Claims (13, 14, 15)

16. A method of delivering a medical device to a target site within the body, the method comprising:
-
constraining to a smaller diameter a tubular structure having proximal and distal ends and a side wall extending therebetween, at least one portion of the side wall having a corrugated surface, the side wall comprising at least one layer of metallic material configured to be heat set to define an expanded shape, wherein the expanded shape is constrainable to a smaller diameter; positioning the constrained tubular structure in a catheter; delivering the tubular structure proximate to the target site; and deploying the tubular structure from the catheter such that the tubular structure assumes the expanded shape. - View Dependent Claims (17, 18, 19, 20, 21)

22. A medical device for treating a target site within the body, the medical device comprising:
a tubular structure having proximal and distal ends and a side wall extending therebetween, at least a portion of the side wall having a corrugated portion that extends partially between the proximal and distal ends, has a first diameter, and has a corrugated surface, the side wall further comprising at least one non-corrugated portion adjacent the corrugated portion, extending partially between the proximal and distal ends, and having a second diameter not equal to the first diameter. - View Dependent Claims (23, 24, 25, 26, 27, 28)
